Upload XAS Spectra to the X-ray Absorption Data Library:

You must be logged in to upload data.

• Uploaded files must be ASCII files no larger than 16Mb with a Header Section followed by a Data Table Section.
• The Header Section contains strings that describe the meta-data for the data file. Ideally, these will follow the XAS Data Interchange Specification. See Example Data Files for this library.
• The Data Table Section contains columns for indvidual arrays. Columns should be separated or delimited by a combination of spaces, tabs, or commas. Each line of the file (ending with a Newline and optional Carriage Return character) corresponds to one row of the Data Table, representing a different energy point for the data. Up to 32 columns will be accessible.
Somewhere in the columns of the Data Table there Must be columns for
1. Energy or Monochromator Angle, in units of eV, keV, or degrees.
2. Arrays that can be used to build $$\mu(E)$$ or mu(Energy). These arrays will be columns in the Data Table that may represent of I_0, I_transmission, I_fluorescence, or mu_transmission, mu_fluorescence. Note that it is OK to have emission modes other than fluorescence -- they will be treated in the same way as fluorescence data.
Names for the columns will be automatically deduced from the data file. These names these may not be perfectly aligned with what you expect the column labels to be. Still, when uploading data, you will be expected to be able to deduce which columns are appropriate and what the column name. During the Verification process, you will be shown plots of the resulting mu vs Energy.

You will be expected to fill in values for some meta-data including:

• Sample Name
• Absorbing Element and Edge
• Monochromator d-spacing or nominal reflecting cut
• Energy units
• Beamline
• Measurement Mode
Some of this meta-data may be guessed from the file headers. In additions, some validity and error checking will be done on these values. Ultimately, the quality of the data relies on you verifying the correctness of these fields.
